The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for Jaconé. We’ve got a slow start, but the second week is where the real swell shows up.
Right now, the water’s at 72°, which is about average for this time of year – nothing unusual.
We start on Tuesday, July 28th, and it’s pretty quiet. The swell is small, only 2ft from the south, with a light offshore NE wind, but the wave energy is weak (197). It’s rideable, but it’s that “just getting wet” kind of session. Wednesday the 29th is similar, with a bit more energy in the afternoon (277) but still only 3ft. Clean, but nothing to write home about.
Thursday and Friday are a bust – the wind turns onshore, and the quality tanks. Thursday the 30th is cross-on with poor conditions, and Friday the 31st gets a bit more size (4ft) but the wind is strong and the period drops to 9 seconds, making it messy and lumpy.
Saturday, August 1st is where things perk up. The morning brings a clean 3ft south swell (12-second period) with a light offshore NE breeze, and the energy is solid (318). It’s a proper clean session for the intermediate crew. Sunday the 2nd goes flat – the swell shifts east and the period drops to 6 seconds, which is weak windswell.
Monday, August 3rd brings a bit more size – 5ft from the ENE – but the period is still short (6 seconds), so it’s crumbly. The morning is clean, but the energy is moderate (310). Tuesday the 4th is similar: 5ft ENE swell with a light offshore, but short period. It’s okay for a grovel.
Now, here’s the one to circle. Friday, August 7th is the standout. We’ve got a solid 6ft south swell, a 12-second period, and the combined energy is pumping (831). The wind is light offshore from the ENE, keeping it clean. That’s real groundswell with some punch. The afternoon is a bit smaller at 5ft, but the energy is even higher (904). This is the best bet of the whole run – a proper long-period south swell with clean conditions. It’s big enough for intermediates, but not too heavy.
Saturday, August 8th is a solid follow-up – 4ft from the SSE with clean winds and good energy (394).
Looking further out, the second week gets serious. By Tuesday, August 11th, we’re looking at 5ft south swells with long periods (13 seconds), and the energy is very strong (up to 1008). The wind stays cross-offshore, so it’s clean. Then Wednesday, August 12th, brings 6ft to 7ft of south swell, periods of 14 seconds, and massive energy (up to 1895). That’s expert territory – 7ft with that much power is only for the experienced crew. The wind is cross-off, so it’ll be lined up, but it’s heavy.
Overall, the first week is a slow burn. The real action is on Friday, August 7th – that’s your day. The following week has some big, powerful swells, but you’ll need your skill.
Catch ya out there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
